No, both Sephardi and Ashkenazi women must count
seven clean days.
However, different Sephardi communities have different practices with respect to the
minimum wait before the clean days. You should consult your Rabbi to determine which practice to follow.
- Ashkenazi communities, and some Sephardi communities mandate a full five days from the onset of niddah.
- In some Sephardi communities, a woman counts a four-day minimum from the last intercourse prior to niddah rather than from the onset of niddah. Furthermore, according to this custom, a woman who douched thoroughly following intercourse does not need to wait any minimum days, but can begin the seven clean days as soon as a hefsek taharah is possible – even after a one-day flow which was preceded by intercourse the night before.
- Some Sephardi communities count from the last intercourse only when a woman became niddah from a stain, but count from the onset of niddah if she had a flow of blood.
